Here are a quick few:
Top knots. Top knots are THE rage. They're cool, and keep hair off your face. Use a foam donut that you buy from Sally's or use as sock with the hole cut in the toes and roll and tuck.
Braids. What better way to wear your hair on the beach than in braids? Whether they're your hair or someone else's, well-maintained braids are an easy, breezy summer hair solution.
Textured styles. Braidouts and twistouts are your friend. Any style that works well with your texture is a good one, given that summer heat often do a number on straight styles.
How are you wearing your hair this summer?
